Commercial Applications of SCNT in Livestock

  • Mark Walton


For most people, the report of the birth of Dolly the sheep in 1996 was their first inclination that cloning animals was not science fiction. Dolly’s arrival was both a seminal moment in the science of reproduction and another step in the evolution of Advanced Reproduction Technologies (ART) in livestock. Somatic cell nuclear transfer (SCNT, aka “cloning”), the process that led to Dolly, is a form of ART that results in exact genetic copies of the donor animal. Livestock produced through cloning are no different than any other animal, and livestock products, e.g., meat and milk, from cloned animals, were found by regulators from Europe, Japan, and the United States to be identical to products from conventional animals. Companies in China, Australia, South America, and the United States provide cloning services to livestock producers and breeders. Cost, burdensome regulatory processes, and public antipathy, especially in Europe, have limited the impact of cloning.
